Black & White 18# H-shaped Automotive Rubber Seal

Black & White 18# H-shaped Automotive Rubber Seal is a mid-sized H-profile edge trim designed to snap over sheet metal flanges and door frames. Its H-shaped cross-section straddles the panel edge, with flexible sealing lips on both inner and outer faces that compress against the mating surface to deliver a dependable dual-sided weather seal while protecting the metal edge from water intrusion and corrosion.

This 18# size sits between compact and medium profiles, fitting a wide range of flange thicknesses on box truck doors, container doors, refrigerated truck and reefer doors, and passenger car doors. The black-and-white two-tone finish makes the installed edge easy to trace during fit-up and maintenance, helping technicians confirm the seal is evenly seated around the full door perimeter.

Extruded from durable EPDM rubber, this H-shaped seal resists ozone, UV radiation, and wide temperature swings. It grips the metal edge securely without adhesive, stays flexible through heat and cold, and provides consistent sealing against rain, wind, dust, and road noise.

Why choose the Black & White 18# H-shaped seal:

- H-profile that clips over panel edges for dual-sided sealing and edge protection

- Versatile 18# size that fits a broad range of flange thicknesses
